Application filed April 17, 1918. Serial No. 229,077.

To all whom it may concern Be it known that I, SAMUEL A. NEIDIoH, a citizen of the United States, and a resident of Edgewater Park, county of Burlington, State of New Jersey, have invented certain Improvements in Machines for WVinding Ribbons on Spools, of which the following is a specification.

One object of my invention is to construct a machine for winding :1 number of typewriter ribbons on spools simultaneously.

A further object of the invention is to insure the'proper winding of the ribbons on the spools and to provide means for measuring the ribbons as they are wound upon the spools.

A still further object of the invention is to provide means for frietionally driving the spools and to provide means whereby the spools can be readily placed in position on the winding mechanism and quickly removed,

therefrom.

Heretofore machines have been devised for winding a single typewriter ribbon upon a spool and means provided for automatically measuring the ribbon, but in every case, as far as applicant is aware, a single spool was used. but by the present invention a series of spools-say six to twelve spoolscan be woundsimultaneously and accurately measured so as to insure the ribbon being of the proper length. The machine is so designed that when the pressure roller is removed the spools can be lifted out of the machine and a new set of spools placed in position. The invention is particularly adapted for use in winding typewriter ribbons, but

'it will be understood that it can be used for winding other ribbons as well.

In the accompanying drawings 2-- Figure 1 is a plan view of my improved machine for winding ribbons and spools;

Fig. 2, is a side view of suflicient of the machine to illustrate my invention;

Fig. 4, is an endview;

Fig. 5, is a perspective View showing the two spools mounted between the driving spindles;

Fig. 6, is a side view of one of the spools upon which the ribbon can be Wound on my improved machine; and

Fig. 7, is an edge view of the same. K

Referring to the drawings, 1 is a power driven shaft on which is a clutch 2 and a belt wheel. This shaft is mounted in bearings 4 on a frame 5. 6 is a pinion which meshes with a gear wheel 7 secured to a spindle 8 and spaced from this spindle 8 is a second spindle 9, also provided with a gear wheel 10, and an intermediate pinion 11 transmits motion from the spindle 8 to the spindle 9. These spindles are spaced a given distance apart and support and drive the several spools a on which the ribbon b is wound.

12 is a presser spindle bearing on the top of the spools, as shown in Fig. 3, and is of sufficient weight to retain the spools in driving contact with the spindles 8 and 9. Consequently, the spools have a three-point contact, as shown in Fig. 5. In order to insure the spindle driving the spools, I utilize the spring of the metal of the flanges c, c of the spools a, as illustrated in Figs. 6 and 7, and form on each spindle 8 and 9 annular ribs 13 and 11, respectively. The periphery of these ribs is slightly beveled, as shown, so that when the operator places the spools on the spindles they will be guided by the ribs into position and the space between the ribs is slightly less than the distance between the flanges of the spools, so that there is a slight lateral bearing of the ribs of the spindles against the flanges of the spools, suifieient to cause the spindles to drive the spools positively.

Itwill be noticed that the flanges of the spindles are narrow so that the spools can be located comparatively close together side by side, and a-number of these spools can be assembled in a comparatively small space. The spindles 8 and 9 are adapted to bearings in the uprights 15 mounted on the base 5, and the presser spindle 12 is mounted in arms 16and 17 mounted on pivots 18 and 18 respectively, secured to the'uprights 15, and the arm 16 has an extension 19 in the form of a handle so that the spindle 12 can be thrown back, as shown by dotted lines in Fig. 4, to allow for the removal of the spools a.

When the spools are in position the projections on the arms 16 and 17 enter sockets 20 in the uprights 15, in the present instance. The presser spindle 12 has annular ribs 21 alining with the ribs 13 and 14 of the spindles 8 and 9, respectively, and the spindle 12 has a narrow bearing surface 22 at each side of the ribs and this surface bears directly upon the periphery of the spools a. The spindles are slightly reduced in diameter beyards desired and the clutch has a pin which tween the surfaces 22 so as to form a guide surface 23 for the ribbon b, insuring the proper winding of the ribbon on the spools, as it will be understood that the ribbon must not be twisted, or strained, so as to form buckles during the winding process, as this is detrimental to the ribbon and makes it unfit for the purpose for which it is intended.

Narrow grooves 24 of slight depth are preferably formed in each driving spindle 8 and 9 adjacent to the flanges l3 and lat, into which the edge of the flange of the spool extends, so that when the spool is once in position it is rigidly held, and in the event of aspool being slightly bent in handling the mechanism will tend to straighten the spool, insuring the proper winding of the ribbon thereon. In some instances the narrow grooves 21 may be dispensed with.

27 is a series of guide rollers under which the ribbon passes tothe spindle 12. These rollers not only act as guides, but also hold the ends of the ribbon against the spindle '12 when it is thrown back, as shown by dotted lines in Fig. at, so that the ribboncan be cut at the spool and the ends will not become detached from the machine, being held between the rollers and the spindles. so that when another set of s'pools is placed in position they can be readily attached to the hubs (Z of the spools. The rollers 27 may form part of a rod 25 adapted to the bearings 26 on the upright 15, or may be loosely mounted thereon, as desired. I

My invention is preferably used in connection with means for measuring the ribbon, so that a given amount of ribbon can be wound upon each spool. As the invention is particularly adapted for winding typewriter ribbons, each ribbon is of a given length, say twelve yards. and the ribbons are guaranteed this length/ In this instance, I have shown one form of measuring device, which consists of a drum 28 mounted on a shaft 29 on which is a worm 30 which meshes with a 'worm wheel 31. which can be lockedto a timing disk 32 ,by a clutch 33. This timing disk can be' set to trip at any number of engages a lever connected to a spring shaft 3% which not only withd 'aws the clutch 33, but also throws the clutch 2 of the driving shaft out of gear and, consequently, stops the shaft 1 and the-mechanism connected therewith from rotation.

The particular mechanism described forms no part of my present invention, as it is a common device for measuring and stopping the feed of a ribbon. Heretofore this device was used in winding a single spool and I not only continue the drum 28, but also the tension rolls 35. 3b and 37, and the guide rolls 38. 39 is a joint catcher, which is pivoted at 10 and actuates a trip l1, which immediately releases the clutches 33 and 2 and stops chine comes to a stop,

the machine, as it will be understood that typewriter ribbon must be a continuous piece, so that it is important that means be provided for detecting any joints, due to piecing of the ribbons, as they are wound from the large reels onto the spools.

In certain typesof machines each ribbon is provided with a hook and an eye and the hooks are arranged to engage a bar 0 on the spool. as shown in Fig. 7. In this case, these hooks and eyes are attached to the ribbon just prior to its being wound on the spools, and the ribbon may be passed over a table on which is a number of punches, which can be automatically operated to secure all of the eyes and hooks in position. The length of the ribbons can be determined so that the ribbons can be out between each pair of hooks, but in other types of machines, where the hooks are not used, then the ribbon is out after a predetermined length has been wound on the spools.

The operation of the machine is as follows The ribbons are made in the ordinary manner and are treated with the ink preparation and are mounted on comparatively large reels. These reels are then lo cated in front of this machine and the ends of the ribbon are threaded over and under the tension rolls and the measuring roll, and finally pass around the upper presser roll 12 ofthe machine and are secured in any suitable manner to the spools. The hand lever 53% on the clutch operating mechanism 81 is moved so that the shaft 1 will be driven by the pulley 3 and this motion will be imparted to the two spindles 8 and 9 and these spindles will drive the spools which have been assembled side by side in the machine, as illustrated in Fig. 2. a certain number of revolutions of the measuring drum has been made the clutches 33 and 2 will be automatically disengaged and the driving shaft 1 will stop, indicating that a certain amount of ribbon has been wound upon the several spools. The presser spindle 12 is of suflicient weight to hold the several spools in frictional contact with the driven spools 8 and 9, insuring the proper winding of the ribbon on the spools. After the mathrown back to the position illustrated by dotted lines, Fig. 4, and in contact with the guide rolls 2? and the several ends of the ribbon are held firmly between this guide roll and the spindle 12. The ribbons are then cut at a point between the spools and the spindle 12. from the machine and another set of empty spools is placed in position on the spindles 8 and 9 and the ribbon is attached to the hubs of the spools "and the spindle 12 is again moved over into a position to press the spools onto the driven spindles 8 and 9, when the above operation is repeated.

\Vhen the spindle 12 is Then the spools are removed Vhile I have shown certain means for measuring the ribbons and special mechanism forthrowing the driving shaft out of action, it will be understood that any suitable means may be used without departing from the essential features of the invention, and, in some instances, only one of the supporting spindles may be driven, but I prefer to drive both spindles as described above.

I claim 1. The combination of two parallel supporting spindles spaced a given distance apart and arranged to support the spools to be wound, one of said spindles being a driven spindle; and a presser spindle for holding the spools onto the driving spindles, one of said spindles having annular ribs spaced agiven distance apart and arranged to frictionallv engage the flanges of the spools.

2. The combination in a machine for winding ribbons on spools, of a frame; two parallel spindles spaced apart. one of said spindles being the driving spindle and hav- 1ng a series of narrow ribs adapted to engage the flanges of a series of spools; and presser means for holding the spools onto the parallel spindles.

3. The combination of a frame; two spindles spaced a given distance apart and arranged to support a series of flanged spools; annular ribs on the spindles spaced a given distance apart and arranged to frictionallv engage the flanges of the spools: a presser spindle, also having a series of annular ribs alining with the ribs of the other spindles and arranged to hold the spools onto the spindles, the three spindles being arranged parallel one with another; and means for driving one of the supporting spindles.

4.
